Introspector/GccCpp/tree-dump.c/char class switch

If we look at the assembly the switch for the node class, we will see the following :

Block L5

L5:

	subl	$12, %esp	 #,
	leal	-56(%ebp), %eax	 #, tmp119
	pushl	%eax	 # tmp119

	movb	%al, -257(%ebp)	 #,

	cmpb	$101, -257(%ebp)	 #, "e"
	je	L32	 #,

Jump to #Block L32 if we are equal to a "e"

	cmpb	$101, -257(%ebp)	 #,
	jg	L30	 #,

Jump to #Block L30 if we are greater than a "e"

	cmpb	$50, -257(%ebp)	 #,
	je	L25	 #,

Jump to block #Block L25 if we are equal to a "2"

	cmpb	$50, -257(%ebp)	 #, // 2
	jg	L31	 #,

Jump to block #Block L31 if we are greater than a "2"

	cmpb	$49, -257(%ebp)	 #, // '1'
	je	L23	 #, // case '1'
	jmp	L29	 #

Jump to block #Block L29 if we have a "1"

Block L31

L31:
	cmpb	$60, -257(%ebp)	 #,
	je	L25	 #,
	jmp	L29	 #

Jump to #Block L25 if we have a "<" else jump to #Block L29

Block L30

L30:
	movb	-257(%ebp), %al	 #, tmp134
	subl	$114, %eax	 #, tmp134
	cmpb	$1, %al	 #, tmp134
	ja	L29	 #,
	jmp	L32	 #\

Subtract "r" from the eax

Jump to #Block L29 Jump Above

Jump to #Block L32 if we are equal to a "e"
